[Asterisk-Users] problem with zyxel prestige 2002

[Mihkel Raba]

Hi

I tried to use Zyxel Prestige 2002 VoIP Analog Telephone Adapter with 
asterisk.
Device registers both phones and i can call out. But incoming calls are 
not working.
Asterisk -> sip show peers shows zyxel, zyxel web interfce shows that 
devices are registered.
But when i do incoming call to zyxel, phones do not  ring and if 
voicemail is configured, calls go
directly to voicemail.

Any suggestions ?
